How many pins are in the XLR jack (3,4,5)? Does the bass have a 1/4” jack. I don’t see it in the electronics photo. Very nice bass!
Congratulations & Compliments on another nice bass added to your collection, George. Wild guess, as I am almost a complete novice, but suppose the absence of the fifth pin may be the source of the hum?
Look forward to seeing the mod back to the 1/4" jack.Looking at your collection.....do you get a lot of sympathetic strings ringing out while you play? I put 30+ basses in a small 12' x 12' bedroom and found I couldn't practice in there with all the droning! So, it's a stunning "store room" but I have to practice in another room.
